The study aims to estimate the incidence of herpes zoster (HZ), proportion of postherpetic neuralgia (PHN) and the economic burden and impact on quality of life, in Japanese adults greater than or equal to sixty years of age.

Total number of HZ cases reported in the study area, overall and within a specific age-group and gender. The following age-groups will be considered: 60-69, 70-79 and ≥ 80 years of age. [ Time Frame: Approximately 1 year ] [ Designated as safety issue: No ]

Occurrence of HZ-associated PHN pain, persisting between 90 and 270 days after the initial visit for this study. [ Time Frame: Day 90 - Day 270 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Occurrence of HZ-associated hospitalisations. [ Time Frame: Day 0 - Day 270 ] [ Designated as safety issue: No ]

Occurrence of HZ-associated any pain, persisting between 0 and 270 days after the initial visit for this study. [ Time Frame: Day 0 - Day 270 ] [ Designated as safety issue: No ]

Impact of the following factors on the development of PHN: - age, - gender, - concomitant disease, - current immunosuppressive therapy, - HZ severity at first consultation, - timing of initiation of treatment with antiviral agent etc. [ Time Frame: Day 0 - Day 270 ] [ Designated as safety issue: No ]

Japanese adults, aged greater than or equal to sixty years, diagnosed with HZ.

Other: Data collection
